Question

A toaster is rated at 620 W when connected to a 140 V source. What current does the toaster carry, and what is its resistance?

A

ohms

Expert Solution

Step 1

Here,

Power = 620W

Voltage = 140 V

Now for the power

P= VI

I = P/ V

I= 620/ 140 = 4.43 A

Now for the resistance

V= IR

R= V/ I = 140 /4.43 =31.60 ohm
