When a capacitor and a resister are connected in parallel how many degrees out of phase are the current flow through the resistor and the current flow through the capacitor?
When a capacitor and a resistor are connected in parallel, the current through the resistor and the current through the capacitor are 90 degrees out of phase. The current through the resistor is in phase with the voltage across it, while the current through the capacitor leads the voltage by 90 degrees. This phase difference results from the reactive nature of the capacitor, which affects how current and voltage relate in AC circuits.
What is the current through the 150 ohm resistor?
It depends on the voltage applied across it. But the maximum current is limited by the power-rating of the resistor (power divided by the square of the voltage).
How much current is needed to produce 50 mA of current through a 240Ω resistor?
To determine the voltage needed to produce 50 mA (0.05 A) of current through a 240Ω resistor, you can use Ohm's Law, which states ( V = I \times R ). Plugging in the values, ( V = 0.05 , \text{A} \times 240 , \Omega = 12 , \text{V} ). Therefore, a voltage of 12 volts is required to produce a current of 50 mA through a 240Ω resistor.
What size of resistor is required to operate the LED from a 9V battery?
In order to determine what size of resistor is required to operate an LED from a 9V battery, first start by knowing the current and voltage required for the LED. That information is available in the LED's specifications. For discussion purposes, lets assume a typical LED at 2.5V and 50mW. The translates to a forward current of 20mA. Build a simple series circuit containing a 9V battery, a resistor of an as yet unknown value, and the LED. By Kirchoff's current law, the current in the LED is the same as the current in the resistor, which is also the same as the current in the battery. This is 20ma. By Kirchoff's voltage law, the voltage across the LED plus the voltage across the resistor equals the voltage across the battery. This is 6.5V. (9 - 2.5) By Ohm's law, resistance is voltage divided by current, so the resistor is 6.5 / 0.02, or 325 Ohms. The nearest standard value to that is 330 Ohms. Cross check the power through the resistor. Power is voltage times current, or 6.5V times 0.02A, or 0.13W. A half watt resistor is more than adequate for this job.
If voltage constant when the current increases what does the resistance do?
In an electric circuit, ratio of current and voltage is constant which is known as the resistance of the circuit. If voltage or current is to be changed the resistance has to be changed. You cannot keep an invariable resistance in the circuit and increase current while keeping voltage as constant.Hence to vary the voltage or current in a circuit different equipments like rheostat,potentiometer are used.
Does voltage flow across or through a resistor?
No. If a voltage is applied across a resistor, a current flows through it.
Is current is drop when it flowing through the resistor?
Current flows in loops, voltage drops across elements. With relation to current, what flows in, must flow out, so no, current is not dropped across a resistor, it flows through a resistor and voltage is dropped across the resistor.
What is the current drop across the resistor?
The correct question is what is the voltage drop across a resistor or the current flowing through the resistor using Ohm's Law where Voltage = Current x Resistance
Does current flow through a resistor or across a resistor?
Normally through the resistor's internal construction. It flows through any part of the resistor that has low resistance- be it anywere. And then there's this. It might be that one should consider that current flows through a resistor and voltage is dropped across a resistor. Perhaps this is where the question began. The former is fairly straight forward. The latter can be vexing. Voltage is said to be dropped across a resistor when current is flowing through it. The voltage drop may be also considered as the voltage measureable across that resistor or the voltage "felt" by that resistor. It's as if that resistor was in a circuit by itself and hooked up to a battery of that equivalent voltage.
What is the use of resistor in the circuit?
A resistor develops a voltage differential when current is passed through it. Ohm's law: Voltage is current times resistance.
How does a resistor affect the flow of electricity in a circuit: does a resistor reduce voltage or current?
A resistor affects the flow of electricity in a circuit by reducing the current that flows through it. This reduction in current leads to a decrease in voltage across the resistor.
Are resistor drops the voltage or current?
Resistors drop voltage by creating a voltage difference across themselves. This voltage drop is determined by the resistance value of the resistor and the current flowing through it, according to Ohm's Law (V=IR). The current passing through a resistor remains constant if the resistor is in series with other components in a circuit.
When a capacitor and a resister are connected in parallel how many degrees out of phase are the current flow through the resistor and the current flow through the capacitor?
When a capacitor and a resistor are connected in parallel, the current through the resistor and the current through the capacitor are 90 degrees out of phase. The current through the resistor is in phase with the voltage across it, while the current through the capacitor leads the voltage by 90 degrees. This phase difference results from the reactive nature of the capacitor, which affects how current and voltage relate in AC circuits.
What is the voltage drop across a resistor of 300 kilo ohm?
What is the amount of current flowing through the resistor? Voltage drop is dependent on the current. Ohm x Amps = Voltage drop
How much voltage is required to run 0.64 A of current through a 240 resistor Use V IR.?
2.7 x 10^-3
How does a resistor limit current or voltage in an electrical circuit?
A resistor limits current in an electrical circuit by impeding the flow of electrons, which reduces the amount of current passing through it. This, in turn, helps regulate the voltage in the circuit by creating a drop in voltage across the resistor.
What is the current through the 150 ohm resistor?
It depends on the voltage applied across it. But the maximum current is limited by the power-rating of the resistor (power divided by the square of the voltage).
