How do you find current if the resistance is not given?
You can find the current by using Ohm's Law, which states that current (I) is equal to voltage (V) divided by resistance (R). If the resistance is not given, you will need to know the voltage and another parameter such as power (P) or conductance (G) to calculate the current. Alternatively, you can measure the current using an ammeter in a circuit.
What is the relationship between power, voltage, and current, and how can it be expressed mathematically using the formula power equals voltage multiplied by current?
The relationship between power, voltage, and current can be expressed mathematically using the formula: Power Voltage x Current. This formula shows that power is directly proportional to both voltage and current. In other words, an increase in either voltage or current will result in an increase in power.
How calculate unknown resistance?
-- Connect a source of known, small voltage across the ends of the unknown resistance. -- Measure the resulting current through the unknown resistance. -- Divide (small known voltage)/(measured current). The quotient is the formerly unknown resistance.
What current will flow through the heating coil when the heater is plugged in?
The current flowing through the heating coil will depend on the resistance of the coil and the voltage of the power source. Using Ohm's Law (I = V/R), where I is the current, V is the voltage, and R is the resistance, you can calculate the current. The higher the voltage or lower the resistance, the higher the current.
How does the voltage across a load is measured in a circuit with alternating current?
The voltage across a load in a circuit with alternating current is typically measured using a voltmeter. The voltmeter is connected in parallel to the load, allowing it to measure the effective voltage or RMS voltage across the load. This value represents the average voltage of the alternating current waveform.
Using Ohm's Law explain how voltage changes in relation to current assuming that resistance remains constant?
how do you use ohms law express conductance in terms of current and voltage?

How do you find conductance using ohms law?
To find the conductance using ohms law,you take the inverse of the resistance(/R)
Constant current generation of linear sweep voltage using op-amp?
When using the Op-amp we get constant current generation of the linear sweep voltage.
What assumption are taken to analyze a transistor using h-parameter?
The output conductance is assumed to tend to infinity and the collector current is assumed to be equal to beta multiplied by the base current.
Why is conductance G?
Conductance (G) is a measure of how easily an electric current can flow through a material. It is the reciprocal of resistance (R), with the formula G = 1/R. Conductance is important in electrical engineering and physics as it quantifies the ease with which charges can move through a medium. Higher conductance indicates lower resistance and better electrical conductivity.
How does ac dc power supplies work?
The mains to the house is an alternating current and this high voltage is stepped down using a transformer. The low voltage secondary alternating current is converted to direct current using 4 diodes wired as a bridge rectifier. The 'lumpy' direct current is smoothed using an electrolytic capacitor to smooth the resulting dc. It may need to be voltage regulated if the circuits it feeds are voltage sensitive.
What is the dimensional formula for current?
One way to calculate current is using ohms law; current equals voltage divided by resistance or: I=V/R Where I is current, V is voltage and R is resistance.
What does the size of a current depend upon?
One way to determine current is to measure it, with an ammeter. Another way is to calculate it using Ohm's law: current = voltage / resistance.
If the resistance of an electric current is 12 ohms and the voltage in the current is 60 V the current flowing through the circuit is?
..using the formula Voltage(V)=Current(I) * Resistance(R) .. we can get the result ...current will be 5 Ampere
How do you verify omh's law using multi tester?
if your looking for current (I) = voltage ./. resistance voltage (v) = current x resistance resistance (r) = voltage ./. current plug in your values calculate them then use meter to see if they match!
