Ammeter
An ammeter is a measuring instrument used to measure the current in a circuit. Electric currents are measured in amperes (A), hence the name. Instruments used to measure smaller currents, in the milliampere or microampere range, are designated as milliammeters or microammeters. Early ammeters were laboratory instruments which relied on the Earth's magnetic field for operation. By the late 19th century, improved instruments were designed which could be mounted in any position and allowed accurate measurements in electric power systems.
History
The relation between electric current, magnetic fields and physical forces was first noted by Hans Christian Ørsted who, in 1820, observed a compass needle was deflected from pointing North when a current flowed in an adjacent wire. The tangent galvanometer was used to measure currents using this effect, where the restoring force returning the pointer to the zero position was provided by the Earth's magnetic field. This made these instruments usable only when aligned with the Earth's field. Sensitivity of the instrument was increased by using additional turns of wire to multiply the effect – the instruments were called "multipliers".

Just A Little Bit
by: ImmatureIt seems you've been kinda down lately
Come here let me talk to you baby
I know it's been driving you crazy
Why did he break your heart?
He's gone but your heart is still aching
If it's too soon I really don't mind waiting
Tell me what you think about making?
Making a brand new start
Baby, don't you cry
I'll be right by your side
And I won't say goodbye
Not like the other guys
Heartache is in the past
You saved the best for last
Your love is all I ask
But if I'm moving too fast, girl
Gimme just a little bit, babe
Just a little bit of your loving
Gimme just a little bit, babe
Just a little bit of your loving
Gimme just a little bit, babe
Just a little bit of your loving
I want all your loving
I must admit
But we can start with just a little bit, babe
Just wanna let you know that
I wanna give you all of my loving
I know it might be kind of sudden
Don't think I'm rushin' you
My love for you baby is strong
I haven't felt this way for so long
With me girl you won't go wrong
Because my love is true
Baby, don't you cry
I'll be right by your side
And I won't say goodbye
Not like the other guys
Heartache is in the past
You saved the best for last
Your love is all I ask
But if I'm moving too fast
Gimme just a little bit, babe
Just a little bit of your loving
Gimme just a little bit, babe
Just a little bit of your loving
Gimme just a little bit, babe
Just a little bit of your loving
I want all your loving
