Units Of Measurement

Question 1

Current

Answer 1

Measuring unit = amp
Symbol = I

Formula I = E÷R

Question 2

Resistance

Answer 2

Measuring unit = ohm
Mathematical symbol = R
Schematic symbol = Ω

Formula R = E ÷ I

Question 3

Conductance

Answer 3

Measuring unit = mho
Mathematical formula = G
Schematic symbol = upside down omega symbol

Formula G = I ÷ R = I ÷ E

Question 4

Power

Answer 4

Measuring unit = watt
Symbol = W

Formula P = I x E Or P = I ² R

Question 5

Capacitance

Answer 5

Measuring unit = farad
Symbol = C

Formula C = Q ÷ E (Q = charge)

Question 6

Voltage

Answer 6

Measuring unit = volt
Mathematical symbol = E
Schematic symbol = V

Formula E = I x R
