Series Circuits - Engineering

Q1:

There are five resistors in a given series circuit and each resistor has 6 V dropped across it. The source voltage

A is 6 V

B depends on the current flow

C depends on the resistor values

D is 30 V

ANS:D - is 30 V

Here, it is no equal resistance. How does it say 30v?

If he gave they are equal resistance, then it becomes 30v, right?

Anybody solve this.
