Year 1 core concepts

Question 1

what is the voltage diver equation?

Answer 1

(Rb/Ra+Rb)xVs

Question 2

how do you calculate resistance in series?

Answer 2

Ra+Rb+Rc=Rtotal

Question 3

how do you calculate resistance in parallel?

Answer 3

(1/Ra)+(1/Rb)=(1/Rtotal)

Question 4

how do you calculate the equivalent circuit values?

Answer 4

1. calculate Voc by using the voltage divider over the two resistors
2. calculate Isc by using Isc=Vs/Ra
3. calculate the Req by using Voc/Isc
