something connects a 16 resistor, 23 resistor, and 34 resistor in series and then connects the arrangement to a 36 v dc source. how much current is in the circuit?

This is more electrical than chemical and I have no idea what 16, 23, and 34 resistors are. Is that ohms or some other unit? If ohms, then

The total resistance of the circuit, ignoring the internal resistance of the batter and other wiring, is the sum of the three resistors; i.e.,
R = 23 + 16 + 34 = ?
Then I = E/R = 36/R = ?
