Solving Problems: Using Ohm\'s law
a. A laptop computer runs on a 24-volt battery. If the resistance of the circuit inside is 16
ohms, how much current does it use?
b. A motor in a toy car needs 2 amps of current to work properly. If the car runs on four
1.5-volt batteries, what is the motor\'s resistance?
c. What is the current in the circuit below?
1002
20V

B) I/V = R so 2/6 which = 0.333
and for C i physically cannot open the pic but good luck and use Voltage = Current / Resistence
