Question
In my physics lab, we have been constructing a different type of circuit each week (i.e., single circuit, resistors in series, resistors in parallel, Wheatstone bridge). On the midterm, we will have to construct each of these circuits by ourselves. I have the diagrams of the circuits, but they are not helpful in indicating which wire plugs into what. How can you explain, in words, how to construct a circuit with resistors wired in series? I need the information to be very detailed (i.e., the wire plugs into the positive or negative hole on the power supply and the other end of the wire plugs into the resistor).The equipment used in lab to construct the series circuit included: 2 digital multimeters (DMMs), a power supply, three color coded resistors in series, an ammeter, a voltmeter, and wires. Explain the case where the circuit is A, C, E. I should be able to figure out the other 2 cases myself.
Thanks!
Explanation / Answer
In a parallel circuit the voltage is always the same across all of the components.
And always connect the ammeter in series to each individual component to
read amps on the ammeter.To measure voltage across the components, and to
measure amps, always connect the ammeter in series. In a parallel circuit,
each parallel circuit is wired + to +, and - to - the voltage is always the same
for a parallel branch. The instructor will give combinations of series and
parallel circuits. But always remember, in a series branch circuit the components
are wired + to - + to -, and parallel components are wired + to + and - to -.
In a series circuit the amps are the same in the circuit, and parallel circuits
the voltage is always the same.
