Numerical Problems

1. Calculating Current Using Charge and Time

Example: If 30 Coulombs of charge pass through a conductor in 3000 seconds, find the current.

Solution:

1. Given:
   Q=30 CQ = 30 \, \text{C}Q=30C, t=3000 st = 3000 \, \text{s}t=3000s
   
2. Formula:
   I=QtI = \frac{Q}{t}I=tQ​
   
3. Calculation:
   I=303000=0.01 AI = \frac{30}{3000} = 0.01 \, \text{A}I=300030​=0.01A
   
   Answer: 0.01 A

2. Determining Resistance Using Voltage and Current

Example: If a potential difference of 60 V is applied across a resistor and the current flowing is 2 A, find the resistance.

Solution:

1. Given:
   V=60 VV = 60 \, \text{V}V=60V, I=2 AI = 2 \, \text{A}I=2A
   
2. Formula:
   R=VIR = \frac{V}{I}R=IV​
   
3. Calculation:
   R=602=30 ΩR = \frac{60}{2} = 30 \, \OmegaR=260​=30Ω
   Answer: 30 Ω

3. Calculating Power in a Circuit

Example: A circuit has a current of 2 A and a resistance of 10 Ω. Find the power consumed.

Solution:

1. Given:
   I=2 AI = 2 \, \text{A}I=2A, R=10 ΩR = 10 \, \OmegaR=10Ω
   
2. Formula:
   P=I2RP = I^2 RP=I2R
   
3. Calculation:
   P=(2)2×10=4×10=40 WP = (2)^2 \times 10 = 4 \times 10 = 40 \, \text{W}P=(2)2×10=4×10=40W
   Answer: 40 W
