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.
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.
To measure voltage drop across a component or connector the voltmeter must be connected in?
it must be connected in parallel as always
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.
Measure the voltage across a voltmeter and a switch?
If the switch is closed (connected) the voltage across it will read 0V. If the switch is open (disconnected) the voltage across it could be anything, it just depends on what the voltage between the wires going into the switch is.

What component is used to measure voltage?
A Voltmeter.
What will happen to voltage in a parallel circuit?
In a parallel circuit the voltage across each component is the same.
Where would you place the meters to measure voltage?
any where across where you think there is voltage present
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.

How is the voltage drop across each resistance of series combination related to the correspoding resistance?
The voltage across each series component is proportional to its resistance, and their sum is equal to the voltage between the ends of the complete series string.
What is mean't by Reverse voltage?
Reverse voltage is voltage is applied in reverse. Instead of the positive voltage going into the anode lead of a component, it goes into the cathode lead of the component.
How do you measure alternating current voltage and resistance?
You measure current by inserting an amp meter in series with the circuit or using a clamp-on meter to measure current by induction. You measure voltage with a volt meter across the supply. You measure resistance in ohms across the resistance. Luckily all these functions are in the same meter in most cases.
