An electric iron has a resistance of 150 Ohms. How much current will flow when the voltage is 120 Volts?

Question

Please help

Answer 1

you want to use Ohm's Law to solve this one!

V = I x R, meaning that

I = V / R

for this set of parameters we have V = 120 and R = 150, making the equation

I = 120 / 150 = 0.8A

meaning that the current flowing through the electric iron is 0.8 amperes

Answer 2

V=IR

This is a simple plug-in and solve.

I= the current flow measured in amps
R= the resistance measured ohms
V= voltage (potential difference across the conductor measured in volts

 

120= I (150)

 

solve for I
