Learning Goal:
To learn to calculate the equivalent resistance of the circuits
combining series and parallel connections.
Resistors are often connected to each other in electric
circuits. Finding the equivalent resistanceof
combinations of resistors is a common and important task.
Equivalent resistance is defined as the single resistance that can
replace the given combination of resistors in such a manner that
the currents in the rest of the circuit do not change.
Finding the equivalent resistance is relatively straighforward if...

a.When two resistors RA and RB are combined in series and connected to a battery it is observed that the ratio of the power dissipated in RA to that dissipated in RB is equal to 10. If this arrangement is dismantled and the same two resistors connected in parallel to the same battery, what is the ratio of the power dissipated in RA to that dissipated in RB in this new circuit? b.How much energy is converted by a 12...

When resistors are in series, each resistor has the same current but the voltage is different for each according to Ohm’s Law. A given circuit consists of two resistors in series connected to a 24.0-V battery. The current in the circuit is 0.0320 A. If R_1=250.0 Ω,and R_2=500.0 Ω. Find the potential difference across each resistor. Find the equivalent resistance. If the circuit in Problem 6 above is reconnected with the two resistors in parallel, the...

When two or more resistors are connected in parallel to a battery, which of these statements is incorrect? (a) the voltage across each resistor is the same. (b) the total current flowing from the battery equals the sum of the currents flowing through each resistor.

A Investigation #11: Non-Identical Bulbs in Series and Parallel All of the circuits you have investigated so far have involved identical bulbs. If two bulbs are identical and one bulb is brighter, then the brighter bulb must have a larger current thru it. Furthermore, the larger current must be caused by a larger potential difference. In this investigation, you will study circuits for which the bulbs are not identical. We will illustrate that two Spherical bulbs are not identical by...
