Equations To Remember

Question 1

Equation for Voltage?

Answer 1

V=IR (Voltage = Current × Resistance)

Question 2

Power Equations

Answer 2

P=IV (Current×Voltage
P=V²/R (Voltage²×Resistance)
P=I²R (Current²×Resistance)

Question 3

Energy?

Answer 3

E=Pt
(Power×time)
E=VIt
(Voltage×Current (power)×time)

Question 4

How to find fully charged RC?

Answer 4

=5RC
(5×Resistance×Capacitance)
(R=Ohm’s, C=Farads)
