There must have been a build up of static electricity, either in yourself or in the trolley. The shock is the spark as it makes its way to earth.

What is an RCD cut the current to a circuit?
RCD cut the current to the circuit while preventing the electric shock
Why ac current is more dangerous than dc?
no actually dc current is more dangerous than ac because dc is a direct current and has no current zero condition ,which is very dangerous and do not leave us if we get shock while ac current leave us when we get shock
What is dynamic current?
it is a flow of charge practically from negative to positive terminal
What are the function scissor in emergency trolley?
to cut of the item or equipment inside emergency trolley, eg: micropore.
What happens to the electromagnet when the circuit is closed?
An electromagnet if formed by pushing current through a coil. If the circuit is truly open, current will cease to flow, thus no electromagnet.
Why sometimes when you are pushing a trolley do you get a small shock?
The shock is due to static electricity jumping across as it heads to earth.
What are the forces acting when pushing a trolley?
Accoridng to Aristotle, the trolley would stop. According to Galileo the trolley would slow down and eventually stop.
What kind of force do you use to move a trolley?
You can move a trolley with a magnetic force (e.g. use magnets to draw the trolley away from it's original position - assuming it is made of a magnetic material), a gravitional force (e.g. rolling the trolley down a ramp) or with an applied force (e.g. pushing the trolley).
How is the shock you receive from a doorknob like lighting?
when you get zapped in the supermarket by your trolley it sends a little bit of energy through the metal in the trolley to your body, and if you get shocked by lightning you get a big shock of energy. but with a metal door handle it is exactly like the shopping trolley and it will send a shock of energy through the metal to your body. i hope this helped as i am only 13 :)
How did the electric transit affect Americans lives?
Charles Van De Poele invented the idea of trolley poles pushing upward against the trolley wire with the first electric transit.
What is pushing the current?
The push behind a current is voltage.
How did the dodgers get their name?
They were named the Dodgers because in Brooklyn they had trains running through the city and people would always have to "Dodge" them That is how they got their name! The early trolleys in Brooklyn were run on DC power. This caused the trolleys to build up excessive electrical current and when the amount became too great the trolley would make a popping noise. This was an advanced warning of an oncoming electrical shock to customers. When this popping was heard the passangers would get off the trolley ASAP to avoid the shock. This activity was known as Trolley Dodging.
Why must a rescuer clear the victim prior to pushing the shock buttom on an AED?
So no other person but the victim gets the shock.
Does direction matter when a force is applied to an object?
Yes. It determines the direction in which change will happen. If I am pushing a trolley along the supermarket aisle, and you push with me, the trolley will go faster. If you push against me it will slow down, and if you push sideways it will change direction.
Why you get electric shock when current flows opposite direction in a conductor?
When current flows in a conductor you do not get an electric shock provided you do not touch the conductor.
Which would make more shock the alternating current or direct current?
direct current
Who is resposible voltage or current for electric shock?
It is impossible to separate the two. The voltage determines the magnitude of the current, and the current causes the damage. So, they are both responsible for electric shock.
