Answer: The correct answer is 770 W.
Step-by-step explanation:
The expression of the power in terms of potential and current is as follows;
P=VI
Here, P is the power, V is the potential and I is the current.
It is given in the problem that A coffee maker uses 7 amps of current and 110 volts.
Calculate the power of a coffee maker.
P=VI
Put I= 7 A and V= 110 V.
P=(110 V)(7 A)
P= 770 W
Therefore, the power of the coffee maker is 770 W.
