Question

An electrical appliance has a resistance of 25 Ω. When this electrical appliance is connected to a 230 V supply line, the current passing through it will be

Answer 1

Resistance = 25 Ω

Voltage = 230 V

Current = Voltage/Resistance

I = V/R

I = 230/25

I = 9.2 A

Thus, if an electrical appliance has a resistance of 25 Ω and when that electrical appliance is connected to a 230 V supply line, the current passing through it will be 9.2 A.

Answer 2

Answer:

9.2 Amperes

Explanation:

Given :

• Resistance of the electrical appliance = 25 ohms

• Voltage or the potential difference across the electrical appliance = 230 volts

To find :

• Current passing through the electrical appliance

Formula time :

• Ohms law = V=I×R

Where,

V = potential difference

I = current

R = resistance

Substituting the values :

230=I×25

I=230/25

I=9.2 Amperes

The current passing through the electrical appliance is equal to 9.2 Amperes

More:

Coulombs law = q=i×t

Where q = charge

I = current

t = time
