Lighting line connections?
In parallel circuit, switch line closed, switch branches closed, bulb shine, switch line disconnect switch, the branch is closed, no light bulb, indicating switch line can control the whole circuit, the switch can control the branch branch.
2 parallel circuit: the circuit elements are connected together, the characteristic is: the current sanctions in the two part of the road branch, respectively through the two branches of the various components.
The characteristic is that the current flowing through one component flows through the other at the same time. For example: small lanterns in the festival. In the series circuit, the closing switch, the two bulbs simultaneously emit light, and the switch is switched off, and the two bulbs are extinguished, indicating that the switch in the series circuit can control all the appliances.
Series circuit: a circuit consisting of elements connected sequentially.
