calculate the total current in the circuit if the supply were: 5 volts, 9 volts, 12 volts, and 15 volts

Question

Answer 1

Hi Ella,

For this circuit you need to combine all of the resistors in series, to do that you just add them together. so the total would be 561.2Ω

Ohms law is V = I R

V = Voltage (volts)

I = Current (Amperes)

R = Resistance (ohms)

solve for the current and then plug in the voltage at each value.

I = V/R

Have a great day!
