What is the current (in amperes) drawn by an 840 W toaster attached to a 120 V outlet?

The current in a series circuit is 15.6 A. When an additional 7.92-Ω resistor is inserted in series, the current drops to 10.8 A. What is the resistance in the original circuit?

When a 24 resistor is connected across a 12 V battery, a current of 482 mA flows. What is the resulting terminal voltage of the battery?

What current ? is needed to transmit 105 MW of power over a transmission line held at a voltage of 25.0 kV? ?=   A Find the power loss ?loss that would occur in the transmission line if a 1.45 Ω line is used to transmit 105 MW of power. ?loss=   W What percent loss does this represent? percent loss:

A 1500 W microwave oven runs off of a 240 V supply. The current drawn is by the microwave is 6.25Amps  a)  If the electricity cost is $0.0925 per kWh, how much does it cost to run the microwave for 5 min?

A toaster is rated at 80.0 W, when connected to a 132.0-V source. What current (in amperes) does the toaster carry? Round your answer to the nearest hundredth of an ampere.
