Question

Resistors examples.

Three resistors are connected in series at a common voltage of 300V: R1 = 100ohm, R2 = 200ohm, R3 = 300ohm.
a) calculate the current I in the circuit
b) calculate the ratio of the individual voltages on the resistors, ie: UR1: UR2: UR3
c) verify that: UR1: UR2: UR3 = R1: R2: R3

I will be very happy if someone writes it to me here with an explanation of how they did it.

thank you in advance.

Answer 1

Multiply the resistances. Example: Two resistors in parallel, 100 and 200 ohms. 100 x 200 = 20,000

Add the resistances. Example: 100 + 200 = 300

Divide the result in Step 1 by the result in Step 2. This gives you the total resistance. Example: 20,000 / 300 = 66.7 ohms.
