A battery of 1 V gives how much energy to each Coulomb of charge? A. Not enough info B. 5 Joules C. 1 Joule D. 0.5 Joules
Artist 52 [7]

C. 1 Joule

Explanation:

Given:

Voltage = 1V

Quantity of charge = 1coulomb

Unknown:

Energy = ?

Solution:

The amount of work done is often related to the energy in a system.

In this electrical circuit, work done is the voltage that moves a particular charge.

    work done = q x v

  q is the quantity of charge

  v is the voltage

the potential difference in circuit is the driving force of charges.

 Work done = energy = qv

inputting the parameters;

   Work done =  1 x 1 = 1J

Two electrodes connected to a 9.0 v battery are charged to ±45 nc. What is the capacitance of the electrode?
mart [117]

Answer:

5\cdot 10^{-9} F

Explanation:

The capacitance of the electrode is given by:

C=\frac{Q}{V}

where

C is the capacitance

Q is the charge on the electrode

V is the potential difference

In this problem, we have

Q=45 nC=45\cdot 10^{-9} C

V = 9.0 V

Substituting into the equation, we find

C=\frac{45\cdot 10^{-9}C}{9.0 V}=5\cdot 10^{-9} F (5 nF)
