Question

What current is taken by a 3 kW electric geyser working on 240 V mains?​

Answer 1

Answer:

Therefore, 12.5 A of current is taken by a 3 kW electric geyser working on 240 V mains.

Answer 2

$\bigstar$ Given

Power = 3 kW

Voltage = 240 V

$\bigstar$ To Find

Current

$\bigstar$ Solution

We know that

$\red{\rm \longrightarrow I=\dfrac{P}{V}}$

Here

• I = Current
• P = Power
• V = Voltage

Units

• I = Ampere (A)
• P = Watt (W)
• V = Volt (V)

According to the question

We are asked to find current

Therefore

We must find "I"

Given that

Power = 3 kW

Voltage = 240 V

Hence

• P = 3 kW = 3000 W
• V = 240 V

Substituting the values

We get

$\blue{\rm \longrightarrow I=\dfrac{3000}{240} \ A}$

$\green{\rm \longrightarrow I=\dfrac{300}{24} \ A}$

Therefore

$\pink{\rm \longrightarrow I=12.5 \ A}$

Hence

$\checkmark$ Current = 12.5 A
