A series circuit contains three 2 cap omega resistors and a 6 cap omega resistor. The current in each resistor is 4 point 0 cap A What is the voltage of the battery in the circuit?

In a series circuit, resistances add: three 2 Ω resistors and one 6 Ω resistor give a total resistance of 3 × 2 Ω + 6 Ω = 12 Ω. Using Ohm’s law, V = IR = 4.0 A × 12 Ω = 48 V. The battery voltage is 48 V, choice D.
