In measuring a voltage, a voltmeter uses some current from the circuit. Consequently, the voltage measured is only an approximation to the voltage present when the voltmeter is not connected. Consider a circuit consisting of two 2060- resistors connected in series across a 50.0-V battery. (a) Find the voltage across one of the resistors. (b) A voltmeter has a full-scale voltage of 50.0 V and uses a galvanometer with a full-scale deflection of 5.45 mA. Determine the voltage that this voltmeter registers when it is connected across the resistor used in part (a). Voltmeter Ry (a) Number i (b) Number i R Units Units ww R F

Consider a circuit consisting of a battery (4.26 Volts) and three resistors in parallel. If the resistances of the resistors are 16.3 Ohms, 17.7 Ohms, and 33.3 Ohms, calculate the current drawn from the battery. Give you answer in milliamperes to at least 3 significant figures.

Two resistors are connected in series with a 9.000 V battery. The resistances are measured to be 2.500 ohms and 3.500 ohms. Calculate the voltage across each resistor.

You have a simple circuit consisting of a battery and a lightbulb (you can imagine that this circuit is contained within a flashlight).  If the total potential difference provided by the batteries in this circuit is 6V, and if you measure the current to be 23.04mA, what is the resistance of the light bulb (created by the thin wire which composes the filament) in units of Ohms?

Consider the network of four resistors shown in the diagram, where R1 = 1 Ω, R2 = 5 Ω, R3 =2Ω,andR4 =6Ω. . The resistors are connected to a battery with an emf V. (a) What is the current flowing out of the battery if the emf is 12 V? (B) What is the voltage difference across the resistor R1? (C) What is the rate of Ohmic dissipation for resistor R2?

A resistor is dissipating 119milliwatts​ [mW] of power. The voltage across the resistor is 26 volts​ [V]. ​(a) What is the value of the​ resistance? Express your answer in units of ohms​[Ω​]using an appropriate SI prefix such that there are only​ one, two, or three digits shown to the left of the decimal. ​(b) What is the current through the​ resistor? Express your answer in units of amperes​ [A] using an appropriate SI prefix such that there are only​ one, two, or three digits shown to the left of the decimal.

All household circuits are wired in parallel. A 1140-W toaster, a 300-W blender, and a 50-W lamp are plugged into the same outlet. (The three devices are in parallel when plugged into the same outlet.) Assume that this is the standard household 120-V circuit with a 15-A fuse. (a) What current is drawn by each device? Itoaster = A Iblender = A Ilamp A (b) To see if this combination will blow the 15-A fuse, find the total current used when all three appliances are on. Itotal =
