Submitting your Answers: If the result is a decimal number use two decimal places after the decimal

point, i.e. : 0.01 or 3.12 and include the zero before the decimal point if there is one.

If the result is in thousands please include the comma "," such as in 10,000.

If the result is a whole number just include the whole number, i.e. 5 or 32 or 540 or 3,400 with no decimal.

Don't add in any blank spaces before or after the answer or it will be read incorrectly!

Problems 1 and 2 refer to the circuit on the left, where

Vs is the power supply voltage or battery and R1 and R2

are two resistors in series.

Problem 1:

The supply voltage for the circuit is Vs = 10V. R1 = 5KOhms and R2 = 1KOhms. Find out the voltage

through R1 and the voltage through R2.

a)V1=V; b)V2=V

Problem 2:

The voltage through resistor R1 is 2V and the current I is 2mA. If resistor R2 is 100 Ohms, find out

the voltage through resistor R2, the total voltage and the value of resistor R1.

a)V2=V; b)Vs=V; c)R1=Ohms.

Problems 3 and 4 refer to the circuit on the left, where

Vs is the power supply voltage and R1, R2 and R3 are

three resistors in series.

Problem 3:

The total resistance in the series circuit is measured to be 5KOhms. If the power supply voltage Vs used

is 10V and the voltages through R1 and R2 are V1 = 2V and V2 =5V, respectively find out: The voltage through R3 (V3) and the values of each one of the resistors.

a)V3=V; b)R1=KOhms; c)R2=KOhms; d)R3=KOhms

Problem 4:

The resistors used in the series circuit above are: R1 = 2KOhms, R2 = 5KOhms, and R3 = 3KOhm.

If the current is measured to be I = 2mA find out the voltage through each one of the resistors and

the voltage of the power supply Vs.

a)V1=V; b)V2=V; c)V3=V; d)Vs=V
