B.
Because it assures that electric appliances are
covered so the current will only go through its
intended path.
C. Because it breaks the circuit when the current
exceeds the maximum value and is no longer
considered safe.
D. Because it uses a resistance wire with a low
melting point instead of an electromagnet.

that includes 27 V battery and a bulb with a resistance
of 3 ohms?
A. 9 A
C. 81 A
B. 18 A
D.0.11 A
20. Why is a parallel circuit better than series circuit?
A. A parallel circuit has an electromagnet.
B. A parallel circuit has more power.
C. A parallel circuit has more than one pathway.
D. A parallel circuit has more than one resistor.
