Question

Electrical power (P) is measured in watts using the formula P = V · I, where V is the voltage in volts and I is the current in amperes. If there are 50 volts running to a light bulb of 110 watts, how much current is flowing through the light bulb? A. 5,500 amperes B. 60 amperes C. 160 amperes D. 2.2 amperes

Answer 1

D)
`Current(I)=2.2 Amperes\\`

Step-by-step explanation:

`Voltage(V)= 50 volts \\\\Power(P)= 110 watts\\\\Current(I)=?\\\\Power(P)=Voltage(V)*Current(I)\\\\110=50*I\\\\I=110/50\\\\I=2.2 Amperes`

Current flowing through the bulb is 2.2 Amperes

Answer 2

Current flowing through the light bulb is 2.2 Amperes

Explanation:

Step 1:

Given that voltage = 50 Volts and power = 110 Watts. Find current using the formula, P = V · I

⇒ I = P/V = 110/50 = 2.2 Amperes
