Question

example of ohms law .

Answer 1

dear see thispic I hope this help u

Answer 2

Let us see this example.

Below we have a circuit with a resistor and a battery again. But this time we don’t know the voltage of the battery. Instead we imagine that we have measured the current in the circuit and found it to be 3 mA (milli Ampere).

The resistance of the resistor is 600 Ohm. What is the voltage of the battery?

By remembering the “VRIIII!” rule, you get:

V = RI
V = 600 Ohm * 3 mA
V = 1.8 V

So the voltage of the battery must be 1.8 V.
