Problem 1. What is the equivalent resistance of the combination of resistors between points a and b in the figure? Note that one end of the vertical resistor is left free.

Consider an electric circuit below that consists of five resistors connected to a battery proving potential difference e =210 mV. The resistances of the resistors are: R1= 4.0 S, R2= 3.0 N, R3= 6.0 N, R4= 2.0 N, and R5= 5.O N. R1 R2 R4 R3 R5 Complete the following calculations and show all steps necessary and making sure it is clear which part you are solving for. a) Determine the equivalent resistance of the circuit. Include all necessary sketches, annotations and labels in this section. b) Determine the total current in the circuit c) Determine potential difference across the resistor R1. d) Determine the power dissipated by resistor R4. Enter the answer to part d) below. Provide your answer in milliwatts with a precision of two places after decimal.

Three resistors are connected in series as shown in the Figure below to a 20 V battery. Resistors,  R1 = 5.5 Ω, R2 = 8.0 Ω and the value of R3 is unknown. If the total resistance of the circuit is 16.0 Ω, a) what is the value of resistor, R3? b) What is the current through each resistor? c) What is the voltage drop across each resistor? Enter each value separated by a comma

circuit with two batteries and six resistors. It should be possible to trace a path that contains one battery but not the other.Calculate the VIRP table for the circuit. You can ignore the resistances of the batteries.

In the circuit shown in figure 1, all the resistors are rated a maximum power of 1.00 W. What is the maximum emf epsilon that the battery can have without burning up any of the resistors?

The figure below shows five resistors and two batteries connected in a circuit. What are the currents I1, I2, and I3? (Consider the following values:  R1 = 1.20 Ω, R2 = 2.16 Ω, R3 = 3.19 Ω, R4 = 4.18 Ω, R5 = 6.18 Ω.  Due to the nature of this problem, do not use rounded intermediate values in your calculations—including answers submitted in WebAssign. Indicate the direction with the sign of your answer.)I1=?I2=?I3=?

If you reverse the direction of the voltage across a resistor (i.e., if the left side was 5V higher than the right side, change it so that now the right side is 5V higher than the left side), what will happen to the current running through that resistor? Group of answer choices The current will go to zero. The current will double. The current will also reverse direction.   How should you connect voltmeters or ammeters to a device you want to measure the voltage across or current running through (respectively)? Group of answer choices Both voltmeters and ammeters should be connected in series. Voltmeters should be connected in series, while ammeters should be connected in parallel. Voltmeters should be connected in parallel, while ammeters should be connected in series. Both voltmeters and ammeters should be connected in parallel.   Electrical devices which do not follow Ohm's law: Group of answer choices are known as non-ohmic devices. do not exist.
