An electric heater is rated at 1330 W, a toaster is rated at 1150 W, and an electric grill is rated at 1530 W.?
An electric heater is rated at 1330 W, a toaster is rated at 1150 W, and an electric grill is rated at 1530 W. The three appliances are connected in parallel across a 120 V emf source.
(a) Find the current in each appliance.
amps x volts = watts.
Watts divided by volts equals amps
heater: 1330 divided by 120 equals 11.083 amps
you do the rest
amps x volts = watts.
Watts divided by volts equals amps
heater: 1330 divided by 120 equals 11.083 amps
you do the rest
References :
P=VI
therefore: I=P/V
Heater current= 1330/120 = 11.08A
Toaster current= 1150/120 = 9.58A
Grill current= 1530/120 = 12.75A
Hope i helped
