Question

The resistance of the element of an electric heater is 44 ohm . How much current should be used by this heater when a potential difference is 220 V?​

Answer 1

★ Given That :

• ➮ Resistance of Element (R) = 44ohm
• ➮ Potential Difference (v) = 220v

★ Need To Find :

• ➲ Current used by the Electric Heater ?

⚘ Formula Used Here :

• ✪ V = IR ✪ [ Ohm's Law ]

________________________

✇ Where :

• ⇒ V = Potential Difference
• ⇒ I = Current
• ⇒ R = Resistance

⌬ Putting Values in Formula :

• ⇥ V = IR
• ⇥ 220V = I × 44ohm
• ⇥ 220 / 44 = I
• ⇥ Current (I) = 5Ampere

✠ Therefore :

» ❝ Current used by electric heater is 5A. ❞

Answer 2

=> The current used by electric heater is 5A.
