Question

Q3.Resistance of an electric iron 50 Ω.4.2A Current flows through the resistance. Find the voltage between two points? electric iron 50 Ω.4.2A Current flows through the resistance. Find the voltage between two points?

Answer 1

Solution"

⏭ Given:

✏ Resistance of electric iron = 50Ω

✏ Current flow through it = 4.2A

⏭ To Find:

✏ Potential difference across electric iron

⏭ Concept:

✏ As per ohm's law, potential difference across a conductor is directly proportional to the current flow through it.

⏭ Calculation:

✒ V = I × R

✒ V = 50 × 4.2

✒ V = 220 volt

____________________________

• V denotes p.d.
• I denotes current
• R denotes resistance
