laboratory connects a 16§Ù resistor, 23§Ù resistor, and a 34§Ù resistor in series and then comes the arrangement to a 36V dc source. How much current is in the circuit?

Answer 1

Is §Ù supposed to be "ohms"?
Is "comes" really the right verb here? You should not begin with the word "laboratory"

The total series resistance is
R = 16 + 23 + 34 = 73 ohms

I = V/R = 36/73 Amperes
Express it as a decimal.
