DC Circuit

Question 1

Current of series circuit

Answer 1

Current at any point of the circuit is the same

Question 2

Potential difference of series circuit

Answer 2

Sum of potential differences across all components in a series circuit is equal to potential difference across the whole circuit

Question 3

Resistance of series circuits

Answer 3

Total resistance of the circuit is the sum of all the resistances of the components in the circuit

Question 4

Disadvantage of a series circuit

Answer 4

Current will cease to flow if there is a break anywhere in the circuit

Question 5

Current of parallel circuits

Answer 5

Current from the source is the same as currents in separate branches of the parallel circuit

Question 6

Potential difference of the parallel circuit

Answer 6

Potential difference across each branch of a parallel circuit is the same

Question 7

Advantage of parallel circuits

Answer 7

1. The components in a parallel circuit receive a larger power as compared to a series circuit.
2. The rest of the components can continue to work even if one of the components breaks down

Question 8

Disadvantage of parallel circuits

Answer 8

1. A larger current will be drawn from the source

2. Power of the source depleted more quickly

Question 9

Transducer

Answer 9

Electronic devices that respond to changes in physical conditions to convert non-electrical energy to electrical energy or vice versa
(Thermistors, light-dependent resistors, thermocouple)
