Given,
- Current (I) = 0.48 A
- Potential difference (v) = 48 V
To Find,
- It's Resistance.
Explanation,
Applying ohms law,
Ohms law says that the current running through the conductor is directly proportional to the potential difference across its extremities as long as the temperature and other physical conditions are constant.
Mathematically,
⟶ V = IR
[ Put the values ]
⟶ 48 = 0.48 × R
⟶ R = 48/0.48
⟶ R = 100 Ω
Therefore,
Resistance = 100 Ω
A current of 0.48 A flows through a conductor when a potential difference of 48 V is applied between its two ends. What is its resistance ?
- Current = 0.48 A
- Potential difference = 48 V
- Resistance.
- Resistance = 100 Ohm's.
- V = IR
- Current as l.
- Potential difference as v.
- Ohm as Ω.
- Resistance as R.
- This question says that current of 0.48 A flows through a conductor when a potential difference of 48 V is applied between its two ends. Afterwards it asks us to find its resistance.
- To solve this question we have to use the given formula. Now according to this formula V = IR ; we have to put the values. Afterwards we get our final result that is 100 Ω
Using formula putting the values we get the following results....
V = IR
48 = 0.48 × R
R = 48 / 0.48
R = 100
Henceforth, 100 ohm is the resistance.
What does Ohm's law states ?
Ohm's law is description of the relationship between current , voltage and resistance.
