A; The base must be positive with respect to the emitter this condition will allow collector current to flow from collector to emitter. If the transistor manage to get saturated the current can flow in both direction. as a switch

Why doesn't current flow through your body when we stand on wood?
For electricity or current to flow through your body, you should be connected to earth. Wood is an insulator, and so when you stand on wood, current cannot flow through your body to earth.
Does current flows through fruits?
If the voltage is great enough a current will flow.
Something that will not let electricity flow through it is a?
Note that "electricity" doesn't flow, only current does, which is one aspect of electricity, does. Current is the flow of electrons. Bad conductor of current, or an insulator.
What is an electric current flow diagram?
This good? the current flows through the battery and light?
Why do people want switches on mechanisms that use electricity?
To control the flow of current - either to make it flow through the circuit or stop the flow through the circuit
How is the NPN transistor different from the PNP transistor?
"P" is for Positive and "N" is for Negative So basically put a PNP Transistor Would use N to Switch P, in the name "PNP" or "NPN" the first character is for the polarity of the Collector-pin, the second for the Base-Pin, and the third for the Emmiter-pin. So if you have a PNP Transistor you can`t just replace it with an NPN as the polarities differ. If you can find a way to change those polarities then sure it could work. The Collector-pin basically receives the bigger current. The Base-pin determines how much of that current will be transferred to the emmiter-pin. So in a PNP the base current could for example be 0V and the Collector 5V, this will allow a free flow of current from Collector to Emmiter, the usage of a transistor in many cases is to switch high current with lower current. The main difference is that a PNP transistor uses "holes" as carriers and an NPN transistor uses electrons as carriers (It is to be remembered that the flow of current is always in the direction opposite to that of the flow of electrons). The difference in the symbol for the two transistors are that the PNP transistor will have an arrow pointed to the base from the emitter, and the NPN has it pointing outside.
Why npn transistor are more using than pnp transistor. Give two reasons?
1. NPN transistors current conductin is by electrons and conventional current flow will be in the opposite direction. 2. Majority charge carriers are electrons whose mobility is almost double than that of holes.
What is charged by having a one way current flow through it?
A battery is charged by having a DC current flow through it.
How does an ac curcuit work if current cant flow through a capacitor?
AC current can flow through a capacitor, it's DC current that can't
What is the steady flow of electrons through a conductor?
The terminology for a steady flow of electrons through a conductor is called the current of the circuit.
What is and electrical current?
current electricity is where electrons flow through a conductor.static electricity electrons do not flow

How does a current flow through a wire?
according to kcl the current flows through a wire
How does a electric current flow through a light bulb?
The electrical current comes into the bulb from the metal side,flow through the filament ,and out the tip.
Is there actually current flowing through the return wire?
Yes, there is a current flow through he return wire in a closed circuit. The only time there is no current flow through the return wire is when the circuit is open.
Why emitter current flows away from base in NPN transistor?
arrows are shown for conventional current, not electron current.
What is flow of electricity through substance?
Current.
