Electricty

Question 1

Current

Answer 1

Symbol - I
Unit- ampere
Unit symbol - A
Measure using- Amneter

Question 2

Potential difference/voltage

Answer 2

Symbol-V
Unit-voltage
Unit symbol-V
Measured using-voltmeter

Question 3

Resistance

Answer 3

Symbol-R
Unit-Ohm
Unit symbol-omega
Measured using-Ohmmeter

Question 4

Bulbs in series

Answer 4

If a bulb blows,none of them turn on
The same amount of currents flows through each bulb in the series
The voltage is split up,depending on the size of the bulb

Question 5

Bulbs in parallel

Answer 5

The lights in your house are connected in parallel,if a bedroom light blows the kitchen light is unaffected
The current is split between the bulbs, if they are the Same size,then the currents is split evenly.
The same voltage flows through each bulb,so they are brighter than those in series.
