Which will normally have the larger resistance a voltmeter or an ammeter?
A voltmeter has the large resistance.The voltage across any component can be measured if & only if the terminals of that component will be open and this will we can acheiv if we connect the high resistance voltmeter across the open terminals of that component to measure the voltage.
The voltage measured directly across an open switch in a circuit will be?
The voltage measured across an open in a series circuit is the equivalent of the sourse voltage.
How should a voltmeter be connected to measure voltage of a component?
Since voltage is electrical potential difference, to measure the voltage across a component, you place the voltmeter across, or in parallel with, the component.
Why do you think as the voltage across a lamp changes the power consumption?
Because the power of a resistive component is directly proportional to the square of the voltage across that component.
How do volts change in a series and parallel curcit?
Series: The same amount of current flows through each component. The voltage drop on each component is determined by the resistance (or reactance for AC) of the component. Parallel: The same amount of voltage is applied to each component, and the current flowing through a component is determined by its resistance (or reactance).

What voltage is measured across an open fuse or switch?
The full circuit voltage
What will happen to voltage in a parallel circuit?
In a parallel circuit the voltage across each component is the same.
How does the voltage across a load is measured in a circuit with alternating current?
It's measured with an AC voltmeter.
How do you measure the current by using multimeter?
The current is the amperage. It is measured in series. Voltage is measured across the line (parallel).
A voltage that has been stepped down is measured across the output terminals of a?
transformer
What is total voltage in a series circuits?
In a series circuit the total voltage is the sum of the voltage drops across all the component in series. When the voltage drops across each the individual components are added up, they will equal the supply (or applied) voltage.
What is the total voltage of 2 1.5 voltage cells where the minus is facing the minus?
1.5V if measured across the + and - terminals, otherwise 0V. When measured at points with identical potential (voltage), there is no difference between voltage levels and no current flows.
