Consider a circuit with three resistors, R1 = 225 Ω, R2 = 155 Ω, and R3 = 135 Ω, connected in parallel with a 24.0-Vbattery. (These are the same resistances and battery as in the series circuit in Example 21-10.) Find (a) the total currentsupplied by the battery and (b) the current through each resistor.
Calculate the magnitude and direction of the durrents in each resistor of fig. 19-58.
There are two solutions to this problem given on the website. However, both are leaveing out steps.
The switch S in Figure 20.27 is closed at t = 0 and the currentat a reference time tref > 0 is Iref. If the circuit is changed asdescribed below and the switch is again closed at t = 0, determinewhether the current I at the same time tref would begreater than, less than, or equal to the original value of Iref.Indicate your answers with G, L, or E, respectively. (a) Boththe battery voltage ε and the resistance R are doubled. (b)The inductance L is doubled. (c) The battery voltage ε, theresistance R , and the inductance L are each doubled.

- Check Your Understanding When using Kirchhoff’s laws, you need to decide which loops to use and the direction of current flow through each loop. In analyzing the circuit in Example 10.7, the direction of current flow was chosen to be clockwise, from point a to point b. How would the results change if the direction of the current was chosen to be counterclockwise, from point b to point a?arrow_forwardIf a current of one- or two-tenths of an ampere were to flow into one of your hands and out the other, you would probably be electrocuted.
