Which of the following statements is/are true about the
circuit?
Resistors in series must have the same current running through
them.
The current coming into a resistor is greater than the current
coming out of a resistor because some current has been used up by
the resistor.
Resistors in parallel must have the same voltage across them
The sum of the voltages across each resistor in series must sum
to zero.
Adding an additional resistor in parallel will always reduce the
equivalent resistance of that portion of the circuit.
