Answer 2

potential difference
symbol: V
unit: V

Question 3

symbol and unit for Resistance?

Answer 3

symbol: R
unit: “ohm”

Question 4

symbol and unit for Current?

Answer 4

symbol: I
unit: A

Question 5

what is the eqn for Current?

Answer 5

I = Q
—
t

Question 6

what’s Kirrchhoffs law in a Series circuit when looking for Current?

Answer 6

I = I = I = I
(I total = I 1 = I 2 = I 3)

Question 7

what’s Kirrchhoffs law in a Series circuit when looking for Volatge?

Answer 7

Vt = V1 + V2 + V3

Question 8

what’s Kirrchhoffs law in a Series circuit when looking for Resistance?

Answer 8

Rt = R1 + R2 + R3

Question 9

what’s Kirrchhoffs law in a Parallel circuit when looking for Current?

Answer 9

I = I + I + I
( I total = I1 + I2 + I3 )

Question 10

what’s Kirrchhoffs law in a Parallel circuit when looking for Voltage?

Answer 10

Vt = V1 = V2 = V3
