Change of ampermeter measurement range

R_p

R_int

I₂

I₁

1. Define values of all variables, besides sought quantity
2. Change units if necessary
3. Click "Calculate"

		variables: R_p - resistance of shunt necessary to change of ampermeter measurement range from I1 to I2 R_int - internal resistance of ampermeter I₂ - new instrument range I₁ - former instrument range
