Question

A 12V battery is connected to an unknown resistor where the current is 5A. Find the resistance.

Answer 1

Answer:

2.4 ohms

Explanation:

Given :

• Voltage or the potential difference across the battery = 12 Volts

• Current passing through the resistor = 5 Amperes

To find :

• The value of resistance across the circuit with potential difference of 12 volts and current of 5 Amperes

Using the ohms law:

V=I×R

12=5×R

R=12/5

R=2.4 ohms

The resistance of the circuit is equal to 2.4 ohms which has potential difference of 12 volts and current of 5 Amperes

Answer 2

Answer :

Given that a battery of 12v is connected to an unknown resistor where is current is 5A.

We have to find resistance.

From the data we have :

Potential difference (V) = 12 v

Current (I) = 5A

Resistance = ?

We know Ohm's law, potential difference is the product of current and resistance.

→ V = I × R

Substituting values,

→ 12 = 5 × R

→ R = 12/5

→ R = 2.4

→ R = 2.4Ω

∴ Resistance of resistor = 2.4Ω

R(S) = R1 + R2 + R3 + ............

1/R(P) = 1/R1 + 1/R2 + 1/R3 + ............
