Answer:
Explanation:
Power =750w
Voltage=220v
Current flowing I=750/220
=3.5 amp (approx)
By ohm's law,
V=IR
=> R=220/3.5.
=> R=750 ohm

Answer: 1) 3.40A
2) 64.7 ohms
Explanation:
P= 750W ; V= 220 VOLTS
P= V x I
I = P/V
= 750/220
= 3.40 A
BY ohm's Law
V= I x R
R=V/I
R= 220/3.40
= 64.7 ohms
THEREFORE CURRENT PASSING THROUGH THE CIRCUIT IS 3.40 A
AND RESISTANCE IS 64.7 ohms
