Ohm’s Law

Use Ohm’s Law to solve the following problems.

1. If the current in a wire is cut by 1/5 then what happens to the resistance? The potential?
2. If the potential in a circuit is multiplied by 3 what happens to the current? The resistance?
3. If a simple circuit has a potential of 20V and a resistance of 30 Ohms, what is the current?
4. If a simple circuit has a current of 25 mA and a potential of 110 V, what is the resistance?
5. If a simple circuit has a resistance of 330 Ohms and a current of 2A, what is the potential?
6. If a simple circuit has a current of 300 micro amps and potential of 400V, what is the resistance?
7. If a simple circuit has a potential of 1V and a resistance of .0005 Ohms, what is the current?
8. If a simple circuit has a potential of 25V and a current of 10A, what is the resistance?
9. If a simple circuit has a resistance of 270 Ohm’s and a potential of 45V, what is the current?
10. If a simple circuit has a resistance of 1000 Ohm’s and a current of 25A, what is the potential?
