Question

find current if power is 2.2 kw and v=220 volts

Answer 1

Given :-

Power = 2.2 kilo watts

or

1 kW=1000 W

2.2kW = 2.2×1000 → 2200 watts

Potential different (V) = 220 volts

To find :-

• Current.

Solution :-

According to the formula.

Power = Potential difference × Current

P= VI

→ 2200= 220× Current

→ 2200/220= current

→ 10= Current

• Current = 10 Ampere.

Answer 2

ANSWER :

Current of circuit = 10 Amperes.

GIVEN :

• Power = 2.2 kw
• V = 220 Volts.

TO FIND :

• Current of circuit

SOLUTION :

Here,

→ Power = 2.2 kw

→ Power = (2.2 × 1000) w

→ Power = 2200 w

→ Potential difference = 220 V

FORMULA TO BE USED :

⇒ Power = Current × Potential difference

Substituting values,

⇒ 2200 = Current × 220

⇒ 220 Current = 2200

⇒ Current = 2200/220

⇒ Current = 10

⇒ Current = 10 A

∴ CURRENT IN CIRCUIT = 10 AMPERES.
