Physics

Draw a circuit with a battery of 90 V is connected to fourresistors, R1 =10 Ω, R2,= 20 Ω , R3 =30 Ω andR4= 40 Ω, as follows. Resistors R1 andR2 are connected in parallel with each other, resistorsR3 and R4 are connected in parallel with eachother, and both parallel sets of resistors are connected in serieswith each other across the battery. (20 Points)

a. Find the equivalent resistor R12, for the partialcircuits R1 and R2,

b. Find the equivalent resistor R34, for the partialcircuits R3 and R4,

c. Find the equivalent resistor R1234, for the entirecircuits with all four resistors R1, R2,R3, and R4

d. Find the current in the circuit with the single equivalentresistor R1234

e. Find the find the current and voltages across each of thepartial circuits with resistors R12,

and R34.

e. Find the current and voltage across each of the fourresistors R1, R2, R3, andR4

f. Find the power dissipated in each of the resistorsR1, R2, R3, and R4
