What else can I help you with?
What type of series connection will produce a high current?
A device with a low resistive load will produce a high current in a series circuit.
What type of connection produce high current?
A device with a low resistive load will produce a high current in a series circuit.
If voltage is increased in a circuit what happens to current series and parallel respectively?
In this case current flows from a high voltage to a lower voltage in a circuit.
What happens if you add more loads to a series circuit?
When you have multiple loads in a series, the resistance of the loads is added together allowing very little current to flow through the circuit to power any of the loads, making for a low amperage circuit. If you have your loads in parellel, the resistance of the loads in the circuit is subtracted which allows more current to flow, making for a high amperage circuit.
Why is a voltmeter not placed inside the circuit?
The voltmeter is connected parallel to the circuit in order to measure the voltage drop across that circuit or sub-circuit. If you were to connect the volmeter series to the circuit, since it is a high impedance device, it would represent an effective open-circuit condition. You would see the voltage available to the circuit, but the circuit would not receive its intended current and it would not function. Contrast this with the ammeter, which you do place series to the circuit in order to measure the current flow through the circuit.

Why might the current in a short circuit be higher than the current in the original circuit?
The current in a short circuit may be very high because the resistance in the short circuit is probably less than the resistance in the original circuit.
What is the current in a coupling circuit for high frequencies?
Maximum.
Why don't we use an ammeter in series?
You do use an ammeter in series. It has a very low resistance, which according to ohms law, makes it ideal for measuring current. You do not use a volt meter in series, as it has a very HIGH resistance and would not allow current to flow. You measure the voltage across a component (or components), and current through a circuit.
When is the current flowing in a circuit said to be very small?
The current flowing in a circuit is said to be very small when it is in the range of microamperes (10^-6 A) or even lower. This low current can be indicative of high resistance or very low power consumption in the circuit.
What does an fuse do in an circuit?
A fuse protects the (expensive) circuit for too high currents. When the current becomes too high the (cheap) fuse melts and the current is stopped, preferably before damage has been done to the circuit.
What causes an elecrtic current to flow in a circuit?
The movement of electron towards the high potential causes electric current to flow in a circuit.
