Question

The resistance of the element of an electric heater is 22 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) = 22ohm
• ➮ 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 × 22ohm
• ➬ 220 / 22 = I
• ➬ Current (I) = 10Ampere

✠ Therefore :

» ❝ Current used by electric heater is 10A. ❞
