Question

1. What does an electric circuit mean ?

2. Calculate the number of electrons constituting one coulomb of charge.

3. A current of 1 A is drawn by a filament of an electric bulb for 10 minutes. Find the amount of electric charge that flows through the circuit.

4. How much work is done in moving a charge of 4 C across two points having a potential difference 10 V.

5. A current of 16 A flows in a metallic wire for 60 minutes. Find the net charge passed in this duration.

6. If five resistance of 4 ohm, 6 ohm, 8 ohm, 10 ohm and 12 ohm are connected in series, then find the equivalent resistance​

Answer 1

AN ELECTRIC CIRCUIT IS A CONTINUOS PATH OF FLOW OF ELECTRICITY

2.Q= CHARGE

  N=1

  E=?

Q=NE

Q=1*1.6*10-19

Q=1.6*10-19 C

3) I=1A

  T=10MIN=3600S

  Q=?

I=Q/T

1=Q/3600

Q=3600C

4)V=10V

  Q=4C

  W=?

  V=W/Q

  10=W/4

  W=40J

5) I=16A

   T=60MIN=3600S

   Q=?

  I=Q/T

 16=Q/3600

57600C=Q
