When applying Kirchhoff's voltage law, if you measure the voltage across a battery from the negative terminal to the positive terminal, it is considered ; when you measure the voltage difference across a resistor R oppositive the flow of current it is considered positive; negative zero; zero negative; negative positive; positive negative; positive

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 1760- 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 6.85 mA. Determine the voltage that this voltmeter registers when it is connected across the resistor used in part (a). ww R Voltmeter Ry F V R

A 5000μF capacitor is charged up until the p.d.  across its plates is 6.0V. It is then allowed to discharge through a 2000kΩ resistor. Calculate the charge on the capacitor after 300 seconds.

You buy a AA battery in the store, and it has an emf of 1.5 V and small amount of internal resistance. While this battery is fresh O its terminal voltage will be more than 1.5 V when it is used in a circuit. O its terminal voltage will be 1.5 V when it is used in a circuit. its terminal voltage will be less than 1.5 V when it is used in a circuit.

The emf of a battery is equal to its terminal potential difference: O under all conditions ○ only when the battery is being charged only when a large current is in the battery only when there is no current in the battery O under no conditions

(a) When measuring the voltage across a resistor and the current through it, the voltmeter and the ammeter should be connected in respectively, to the resistor. series and series series and parallel O parallel and series O parallel and parallel (b) The resistances of an ideal voltmeter and ammeter should be infinity and zero infinity and infinity zero and infinity zero and zero respectively. Hint: Voltage is the measure of difference of the potential between two different points. Current is the measure of the flow of electrons.
