WebThe potential difference or voltage, is simply an indicator of how much potential energy is gained or lost per coulomb, when it moves from one point to another. It can also be thought of as how much work needs to be done to transfer the potential energy per coulomb from one point to another. WebUsing Current formula. I = V/R. I = 20/4. I = 5. Answer: Current flowing in the circuit is 5 Ampere. Example 2: The total current flowing in an electric circuit is 50Amp whereas the resistance of the wires is 14Ohm. Using the current formula find the potential difference.
