HW (2)- Ohm’s Law :

1) What is the current through a 6.8 Ω resistor if the voltage drop across it is 12V?

- I want to solve number 1 ?

2) What is the voltage across a 47Ω resistor if the current through it is 35 mA?

- I want to solve number 2 ?

3) How much resistance is required to limit the current to 2A if the potential drop across the resistor is 6V?

- I want to solve number 3 ?

4) A washing machine is rated 4.2A at 120V. What is its internal resistance?

- I want to solve number 4 ?
