Calculate the total resistance of three resistors, R1 = 3 ohms & R2 = 1.2 kilo-ohms connected in parallel, then with R3 = 100 ohm in series ? Find the current flowing from a 24 v DC source when connected to these resistors.
Added by Dana A.
Step 1
The formula for total resistance (Rt) of two resistors in parallel is given by: 1/Rt = 1/R1 + 1/R2 Substituting the given values: 1/Rt = 1/3 + 1/1200 = 0.333 + 0.000833 = 0.334 ohms^-1 Therefore, Rt = 1/0.334 = 2.994 ohms Show more…

Resistors are given as R1 = 10 ohm, R2 = 20 ohm, and R3 = 30 ohm. Calculate the effective resistance when they are connected in series. Also calculate the current flowing when the combination is connected to a 6 V battery.

Three resistors R1 = 2 ohm, R2 = 4 ohm, and R3 = 8 ohm are connected to a source with a terminal voltage of 6V. Find the current that would pass through each resistor and the voltage across each if they are connected in a) series b) parallel.
