Question #348430

A parallel circuit is set up With three resistors: 5 ohms 10 ohms and 15 ohms. If the power supply to the circuit is 30 V what is the current across each resistor and what is the total current through the circuit?

Expert's answer

"I_2=\\frac{V}{R_2}=\\frac{30\\:\\rm V}{10\\:\\Omega}=3\\:\\rm A"

"I_3=\\frac{V}{R_3}=\\frac{30\\:\\rm V}{15\\:\\Omega}=2\\:\\rm A"

"I_{\\rm net}=I_1+I_2+I_3\\\\\n=\\rm 6\\: A+3\\: A+2\\: A=11\\: A"
