Question

An electric room heater draws a current of 2.4 ampere from from the 120 volt supply line what current will this room heater draw when connected to 240 volt supply line

Answer 1

hiiii mate here is the answer

HEY!!

____________________________

▶️An electric room heater draws a current of 2.4 A from the 120 V supply line.

▶️So current, I = 2.4 A

▶️Voltage, V = 120 V

▶️Resistance, R = V/I

▶️R = 120/2.4 = 50 Ω

⏩The resistance will remain constant unless the room heater is changed.

⏩Now when the room heater is connected to the 240 V supply line, the current drawn is:

▶️I = V/R

▶️I = 240/50 = 4.8 A

▶️▶️So the room heater will draw a 4.8 A current when connected to the 240 V supply line.

hope it may help you
