If a diode is connected to a battery and a lamp what happens when the diode direction is reversed?
I diode allows current to flow in only one direction. Therefore, if a lamp is "on" in a DC circuit, and the diode in series with the lamp is reversed, the light will be turnned off due to the diode blocking current flow (unless the voltage is above the breakdown voltage of the diode - if this is the case, the diode will fail). If this is an AC circuit, every half cycle the diode will turn on, then the next half cycle it will turn off. To your eye, the bulb will most likely appear slightly dim due to this on then off cycling. If the diode is reversed, there will be no apparent change. The difference is the half cycle the diode would have been off before reversing, it will now be on, etc.

What happens when your phones battery looks fat?
Your battery is probably failing and trying to explode.
What happens if you put a battery in the freezer?
it charges
What happens when you disconnect the wire from the battery?
Disconnecting a wire from a battery would break the circuit. If the battery was powering a bulb, the lamp would go out.
What happens when a battery gets hot?
It starts to work again.
What happens to the diode if it has high piv?
It can be connected in high reverse bias voltage .
What happens to the heating effect when the direction of current is reversed?
When the direction of current is reversed, the heating effect remains the same. The amount of heat generated is determined by the magnitude of the current and the resistance in the circuit, independent of the direction of the current flow.
What happens to the direction of a magnetic field around an electric current when the direction of the current is reversed?
The direction of the magnetic field around the electric current also reverses when the direction of the current is reversed. This is determined by the right-hand rule, where the direction of the magnetic field is perpendicular to the direction of the current flow.
What happens if you charge a 12 volt battery backwards?
You cannot charge it connected backwards. You will destroy the battery.
What happens when the electric current is reversed on am electromagnet?
When the electric current is reversed on an electromagnet, the direction of the magnetic field is also reversed. This means that the north and south poles of the electromagnet switch places. This change in polarity can have various effects depending on the application, such as reversing the direction of motion in a motor or changing the direction of attraction or repulsion in a magnetic system.
What happens when a battery is connected wrong on a 1997 mercury villager?
you can blow fuses or the battery Possible computer damage.
What happens to a current carrying wire in a magnetic field when it is reversed?
When the direction of the current in a wire is reversed in a magnetic field, the direction of the force acting on the wire also reverses. This causes the wire to move in the opposite direction within the magnetic field.
What happens to the force generated by the circular coil of Relay if current direction is reversed?
As long as the amperage stays the same, the force in the relay stays the same regardless of direction of the current.
What happens when a battery is connected to a alternating current source?
this action is very dangerous and should not be considered.
What happens to a current carrying wire in a magnetic field if the current is reversed?
In that case, the magnetic field caused by the current would also be reversed. As for the wire itself, it would feel a force in the opposite direction, due to the interaction of the magnetic fields.
What happens when a player plays the wild reverse card in a game of Uno?
When a player plays the wild reverse card in Uno, the direction of play is reversed, meaning the order of turns changes to the opposite direction.
What happens to the compass needle in Figure 7-11 when the current through the conductor is reversed?
When the current through the conductor is reversed, the magnetic field around the conductor will also reverse. As a result, the compass needle in Figure 7-11 will deflect in the opposite direction compared to when the current was flowing in the original direction.
What happens when a bulb ammeter battery and switch are put connected together?
the bulb will glow and ammeter will show the reading
