Determine the voltage across R2 in the figure below, if the source is 6V, the Zener is 5.2V, R1= 10k ohms, and R2= 10k ohms.

Two resistors (R1 and R2) are used to build two circuits, one in series and the other in parallel. When connected inseries with a battery of 8,0 V; you read the voltage in R1as 2,0 V with a multimeter. When connected in parallel, you read the current in R2as 1,5A. Find the values for the two unknown resistors.

A 20-ohm resistor is connected in parallel with a variable resistor R. The parallel combination is then connected in series with a 4-ohm resistor and connected across a 240 V source. Determine the minimum value of Rif the power of R is equal to the power taken by the 4-ohm resistor.
