If conductor pass energy then my question is that heat energy change int electrical of wire?
Yes, when a conductor passes energy through it, such as in the form of heat, the conductive material can convert that heat energy into electrical energy. This process can occur in materials with high electrical conductivity, where the thermal energy can excite the charge carriers, leading to the generation of electrical currents.
What is the current through a wire that has a resistance of 30 ohms if the voltage is 90 volts?
The current through the wire can be calculated using Ohm's Law, which states that current (I) equals voltage (V) divided by resistance (R). In this case, the current would be 90 volts divided by 30 ohms, which equals 3 amperes.
How ac current pass through capacitor?
Alternating charged current arrives at one terminal on the cap. The load to ground is connected at the other terminal of the cap. Actually 'alternating' can be a confusing electrical term to some folks. Think of the charged current as a wave that delivers this positive current from the bottom to the top of the wave and retreats or falls off at the bottom of the other side of the wave. This condition is caused from the rotating action of the rotor turning inside the stator fields in a generator. The ground through the load is attracted to the positively charged electrons at the barrier of the cap at the top of the wave from the generator. Now. Think charge separation on the ground side. As the electrons become excited on the ground side of the cap at the barrier across from the positive charge (attraction), a vacancy of non-charged electrons has occurred downstream at ground. When the positive charge and current falls at the bottom of the wave from the generator side, the excited electrons at the barrier of the cap on the ground side are now positive (charge separation) and move to power the load and fill the vacancy to ground. This is also the reason for the delay of current and charge moving through a cap to ground. A larger barrier equals a longer delay (faud rating). Nothing but magnetic field attraction between electrons has happened at the cap barrier. This is why a DC current cannot move through a cap. It has no wave. If we pulse the DC, we can get it to move through the cap, but at a lower efficiency than AC. calllowayengines dot com
How to calculate the current in a circuit?
To calculate the current in a circuit, you can use Ohm's Law, which states that current (I) equals voltage (V) divided by resistance (R). The formula is I V/R. Simply plug in the values for voltage and resistance to find the current flowing through the circuit.
What is the current in amps flowing through the circuit?
To determine the current in amps flowing through the circuit, you need to use Ohm's Law, which states that current (I) equals voltage (V) divided by resistance (R). The formula is I V / R. Measure the voltage across the circuit and the total resistance of the circuit, then plug the values into the formula to calculate the current in amps.
Is it true that current is a the rate of flow of electrons?
Yes, current is the flow of electric charge, typically carried by electrons in a conductor. It is measured in amperes and represents the rate at which electrons pass through a given point in a circuit.
State ohms law?
Ohm's Law states that the current through the conductor is directly proportional to the potential difference between its ends provided its temperature and other physical conditions remain constant
If conductor pass energy then my question is that heat energy change int electrical of wire?

This process can occur in materials with high electrical conductivity, where the thermal energy can excite the charge carriers, leading to the generation of electrical currents.
Does the amount of electric current flowing in a conductor depend in part on the pressure under which it flows?
Yes. Pressure being voltage. Voltage divided by resistance equals current.
What is the current drawn when you have a single phased load of 200KW is supplied at 500v through an overhead line with a resistance of 0.1ohm per conductor?
If the voltage is 500 volts, and the power is 200 kilo-watts, then the current is 400 amperes. (Watts equals Volts time Amperes)The resistance of the conductor has nothing to do with this calculation, but that fact that the conductors are 0.1 ohms means that the voltage drop across each conductor is 40 volts. (Volts equals Amperes times Ohms) Since there are two conductors, the total voltage drop is 80 volts, and the voltage available to the load will be 420 volts.
If the voltage is doubled the ampacity of a conductor is?
Unchanged. The conductor's ampacity is affected by its composition (copper, aluminum, etc.), cross-sectional area, and temperature, not by the supply voltage. The ampacity is limited because any conductor has resistance. When the conductor carries a load (supplies current), the conductor essentially becomes a resistance heater, and gets hot. At some point the temperature will become dangerous, either causing the conductor to melt or damaging the insulation or surrounding materials. The voltage dropped across a conductor that is supplying current to a load is computed by the following formula: E=I^2 X R Or, voltage dropped equals current through the conductor squared times the resistance of the conductor. Notice that the supply voltage is not even part of the equation. All the mentioned parameters - composition, cross-sectional area, and temperature affect its resistance. The ampacity of a conductor installed in a building can also be regulated by law, so, even though a conductor may pass a certain amount of current local laws may prohibit it's use anyway.
What is a circuit with several current paths whose total current equals the sum of the currents in its branches?
This is a parallel circuit, each of the parallel current paths draws a certain current, and the input current equals the output current, so the sum of all current through each path has to equal the total current.
What is the current through a wire that has a resistance of 30 ohms if the voltage is 90 volts?
The current through the wire can be calculated using Ohm's Law, which states that current (I) equals voltage (V) divided by resistance (R). In this case, the current would be 90 volts divided by 30 ohms, which equals 3 amperes.
Why do battery terminals heat up when connecting 6 volt batteries in series?
Excessive current is the cause. A battery delivers an electrical potential difference (the voltage across the two battery terminals when connected). When the two battery terminals are connected by something which conducts electricity (a "conductor"), an electrical current will flow from one lead to the other; a flow of electrons is established across the terminals. When this electron flow is unrestricted, or in other words when it flows through ONLY the conductor and no other parts, the current is then as high as it can be, which for two 6-volt batteries (12 volts total) would be 12 amps (12 volts divided by zero "ohms" of resistance equals 12 amps) of speed, or "current" as it is correctly termed. 12 amps is an extremely large current and would fry most any electrical part in a typical device (dye to literally the friction of electrons crashing through particles) such as a light, and has the potential to stop your heart and/or loose conciousness and/or receive severe burns. The current therefore needs to be slowed using a small device called a resistor, down to a much smaller and more practical fraction. This is why your battery terminals heat up - use a resistor, they can be bought at Radioshack for pennies, and do your simple math of Ohm's Law (voltage divided by resistance in ohms equals current, current times resistance equals voltage, etc.).

This is a parallel circuit, each of the parallel current paths draws a certain current, and the input current equals the output current, so the sum of all current through each path has to equal the total current.
What is the voltage drop of a 1k ohm resistor?
It depends on the current going through it. Ohm's law: Voltage equals current times resistance.
What is the current through a 1.5k resistor with voltage of 3V across it?
Two milliamperes. Ohm's law: Current equals voltage divided by resistance.
