You have aready stated that the current through the LAMP is 0.625 A. If the microwave is some other part of the circuit, it will have the same current if it is in series wth the lamp. If it is in parallel wth the lamp, you need to tell us more about the circuit, including the resistance of the microwave.
A 100 W lamp is connected to 120 V, and its current is measured. A resistor is added to the lamp to reduce the current to half its original value. (a) What is the potential difference across the lamp? (b) How much resistance was
An electric drill operates at a potential difference of 120V and draws a current of 1.5 Amps. If it takes 50 seconds to drill a hole in a piece of steel,calculate the amount of electrical energy used by the drill in that time.
An incandescent lamp is marked '120v,75W' a)what is the current in the lamp under normal condition of operation? b)How much does it cost per hour to operate the lamp if the price of electrical energy is $6.00 per unit? Please stop
