electricity equations

Question 1

the equation that links charge flow, current and time

Answer 1

charge flow (c) (coulombs) = current (A) x time (s)
Q = It

Question 2

what is the equation for potential difference?

Answer 2

potential difference (V) = current (A) x Resistance

Question 3

what is the equation for when potential difference is shared?

Answer 3

Vtotal = V1 + V2 + …

Question 4

what is the equation for the current being the same everywhere?

Answer 4

I1 = I2 = ….

Question 5

what is the equation for when resistance adds up?

Answer 5

Rtotal = R1 + R2

Question 6

what is the equation that links energy transferred, power and time?

Answer 6

Energy transferred (J) = Power (W) x Time (s)
E = Pt

Question 7

what is the equation that links energy transferred, charge flow and potential difference?

Answer 7

Energy transferred (J) = charge flow (c) x potential difference (V)
E = QV

Question 8

what is the equation that links power, potential difference and current?

Answer 8

Power (W) = Potential difference (V) x Current (A)

Question 9

what is the equation that links power, current and resistance?

Answer 9

Power (W) = Current^2 (A) x Resistance
P = I^2R

Question 10

what is the equations that link that potential difference across secondary multiplied by current in secondary an p.d. across primary and current in primary?

Answer 10

p.d across secondary coil (V) x current in secondary coil (A = p.d across primary coil (V) x current in primary coil (A)

Question 11

what is the equation that links potential difference, current and resistance?

Answer 11

V = IR
Potential difference (V) = Current (A) x Resistance
