The circuit is basically a normal light dimmer circuit, but the potentiometer is replaced with LDR resistor which changes it's resistance depending on the light level. Nale's per. Two or more resistors are simply added in series to obtain the equivalent resistance. A "parallel" circuit has two or more paths for the electricity. In order to find the current I(t)through the circuit, we can treat the capacitor as having a complex impedance, and then use Kirchhoff’s laws to analyze the circuit. It is measured in Coulombs/second which is called Amperes (symbol: A). You have to use two kids per lab team to do this - unless you order extra light bulbs/LED. Equipment:. A light bulb can be illuminated when a battery is connected in a simple circuit, but only when the circuit is 'complete', meaning the flow of electricity forms a continuous 'loop'. Yes, this is why we have parallel circuits in our houses rather than series. RE and R 1 are parallel, therefore the equivalent resistance is the reciprocal of.
