Circuits

Question 1

What are the equations in circuits?

Answer 1

Charge= current x time (Q= I x T)

Current= charge / time ( I= Q / T )

Time= charge / current ( T= Q / I )

Question 2

What are the equations for a circuit p2?

Answer 2

Potential difference= current x resistance (Volts)

Current= potential difference / resistance
( I Amps)

Resistance= potential difference / current
(Ohms)

Question 3

What is ohms law?

Answer 3

I = V / R

Question 4

What is the equation for PD across a comp?

Answer 4

PD across a component = energy transferred (J) / charge
