Choose true or false for each statement regarding resistors in a circuit.
If you connect two different resistors in series in a circuit, then the current
that flows through each of them is the same.
8 If you connect two different resistors in parallel in a circuit, then the
voltage across each of them is the same.
8 Two identical resistors in parallel have half the resistance of each individual
one.
