Question

Find the current for a circuit which contains a resistor of 600 Ohms connected to a 30 volt power supply *
1 point
0.5 A
0.05 A
20 A
2 A

Answer 1

Given ,

Resistance (R) = 600 ohm

Potential difference (v) = 30 volt

We know that ,

The ohm's law states that the current flows through the conductor is directly proportional to the potential difference of the battery

$\mapsto \sf V \propto I \\ \\ \mapsto \sf V = I R$

Where , R is the constant of proportionality called resistance of the conductor

Thus ,

30 = I × 600

I = 30/600

I = 0.05 amp

Hence , the current flows through the conductor is 0.05 amp

Answer 2

Answer of the question is 0.05A

_________________________________

Solution :

✴ Given :-

• Resistance of resistor = 600Ω
• Potential difference = 30V

✴ To Find :-

• Magnitude of current flow in circuit

✴ Concept :-

▪ As per ohm's law, current flow through conductor is directly proportional to the applied potential difference.

Mathematically,

$\bf{\large{V=I\times R}}$

• V denotes potential difference
• I denotes flow of current
• R denotes resistance

✴ Calculation :-

=> V = I × R

=> 30 = I × 600

=> I = 30/600

=> $\underline{\underline{\bf{I=0.05\:A}}}$
