Question

An electric iron draws 2.2 amperes of current from a 220 volt source find the resistance and power

Answer 1

Answer:r=100ohm p = 484 w

Explanation:

V=it

P=V2/r

Answer 2

GIVEN

• Voltage (V) = 220 V
• Current (I) = 2.2 A

FORMULA TO BE USED

• P = V × I
• R = V/I

RESISTANCE CALCULATION

R = 220/2.2

R = 100 ohms

POWER CALCULATION

P = 220 x 2.2

P = 484 W

RESULTS

• Resistance = 100 ohms
• Power = 484 W
