Question

the potential difference across the bulb is 220 V and the current flowing through it is 22 Amp. find resistance?​

Answer 1

Answer:

44

Answer is C.

According to Ohm's law, V = IR. That is, R = V/I.

Here, V = 220 V and I = 5 A.

Therefore, R = 220/5 = 44 ohms.

Hence, the resistance of the heater is 44 ohms.

Answer 2

Answer :-

• Resistance offered is 10 Ω.

Explanation :-

Given :

• Potential difference (P) = 220 V
• Electric current (I) = 22 A

To find :

• Resistance (R)

Solution :

Using Ohm's law V = IR

Where,

• V = Potential difference
• I = Electric current
• R = Resistance

Substituting the values,

⇒ V = IR

⇒ 220 = 22 × R

⇒ 220/22 = R

⇒ R = 10 Ω

• Resistance offered is 10 Ω.
