Question
Consider the three circuits shown above. All the resistors and all the batteries are identical.
(True/False) The current through a resistor is the same in circuits A and C.
(True/False) The voltage across a single resistor in circuit C is twice the voltage across a single resistor in circuit B.
(True/False) The current through a resistor is the same in circuits A and B.
(True/False) The power dissipated in circuit A is twice the power dissipated in circuit B.
(True/False) The total power dissipated in circuit C is twice the total power dissipated in circuit B.
Explanation / Answer
false -in parallel the voltage remains sme and not the current
false - reason is same as above
true - the current goes same in series if their value is same
true -as equi resistance is double in B and formula is V^2/r
false - it will be 4 times
