Current is calculated on the load. If your question on transformer primary current, then use the formula N1I1=N2I2, where N1 and N2 are primary and secondary coil turns and I1 and I2 are current in respective coils. This is very basic simple formula. You have reframe your question more specifically.

How do you calculate voltage per winding?
To calculate voltage per winding in a transformer, you can use the formula ( V_{winding} = \frac{V_{primary}}{N_{primary}} \times N_{winding} ), where ( V_{primary} ) is the primary voltage, ( N_{primary} ) is the number of turns in the primary winding, and ( N_{winding} ) is the number of turns in the winding of interest. Alternatively, for transformers, the voltage ratio can be determined by the turns ratio: ( \frac{V_{secondary}}{V_{primary}} = \frac{N_{secondary}}{N_{primary}} ). This allows you to find the voltage across any winding based on the primary voltage and the turns ratio.
What is the gross primary productivity equation used to calculate the rate at which plants convert solar energy into chemical energy through photosynthesis?
The gross primary productivity equation used to calculate the rate at which plants convert solar energy into chemical energy through photosynthesis is: Gross Primary Productivity Rate of Photosynthesis - Rate of Respiration.
How do you calculate the secondary V if the primary V is 220V and the primary N is 2000 turns and the secondary N is 100 turns?
A turns ratio of 2000 to 100 is a 20 to 1 reduction in voltage, so the secondary, if the primary is 220 V, must be 11 V.
How do you calculate CT primary current?
To calculate the primary current (I_p) in a current transformer (CT), you can use the formula: I_p = I_s / CT ratio, where I_s is the secondary current and the CT ratio is the transformation ratio of the CT (primary turns to secondary turns). For example, if the secondary current is 5 A and the CT ratio is 100:5, the primary current would be I_p = 5 A / (100/5) = 25 A. Always ensure the CT is being operated within its specified parameters for accurate readings.
How should I calculate this. A single phase transformer is rated at 99kVA The primary voltage is 6.6kV and the secondary voltage is 220V Assume no losses and calculate The full load primary current?
First find the ratio of the transformer. 6600/220 volts. Second find the secondary current, I = W/E, 99000/220. Third divide the secondary current by the transformer ratio. The answer will be the primary current. To check your answer (W (or VA) = V x A) multiply the primary current times the primary voltage and the secondary current times the secondary voltage and they should both equal the transformer's kVA.
What is the gross primary productivity formula used to calculate the amount of energy produced by plants through photosynthesis in an ecosystem?
The gross primary productivity formula is: Gross Primary Productivity Rate of Photosynthesis - Rate of Respiration. This formula calculates the amount of energy produced by plants through photosynthesis in an ecosystem.

How do you calculate current on the primary side of a transformer only knowing the turns ratio and the voltage ratio?
The primary current on a loaded transformer depends on the secondary current, which is determined by the load. So, if you know the secondary load current, then you can use the turns ratio of the transformer to determine the primary current:Ip/Is = Ns/Np
