Why is the wattmeter connected at the primary side of the transformer?
In general, you can install a wattmeter on the primary or the secondary side of a transformer (it depends what you are trying to measure). But if you are conducting an open- and short-circuit test (to find the transformer's losses), then the wattmeter is connected to the primary side because you want to measure the total (primary + secondary) losses and that is only achievable from the primary side.
What is the formula for total current in a series circuit?
Current = (Voltage across the circuit) divided by (Total resistance of the circuit). The current is the same at every point in the series circuit.
What is the total current of the circuit if voltage is 12 R1 is 100 Ohm and R2 is 200 Ohm?
As you don't specify how R1 & R2 are connected, it is impossible to give an answer to your question.
Why you take the conjugate of current in complex power?
In order to calculate the complex power of a circuit, the conjugate of current is used. The Vrms of the circuit is multiplied by the complex conjugate of the total circuit current.
Three electric cells each have a voltage of 1.3Vwhat is the total voltage of the three cells if the cells are connected in parallel?
voltage is still 1.3V in parallel circuit, voltage stays the same but current adds up in series circuit, voltage adds up but current stays the same
Can I connect current transformer in series?
CT(Current Transformer) is used to measure current flowing in the circuit. Current can be fully drawn or sensed in series condition. That's why , it is connected in series. In parallel , the current is divided; and hence the total current cannot be measured)
Does led lighting require a transformer per light or one per circuit?
One transformer should feed several led's in parallel, but you have to work out how much current each one will take, total it up, and then get a transformer with the correct output voltage and that can supply the total current. Don't exceed the transformer max current or it may fail through overheating
How is an ammeter connected in a circuit in order to read the current flowing in the circuit?
In series with the circuit and never in parallel. The reason being that it will cause the circuit total resistance to drop which will make the circuit draw excessive current. That's a short circuit actually.
The total current that flows through a circuit is the same as the current that flows through each individual resistor connected in series?
True
When an ammeter is connected to measure current circuit current will decrease sightly because R total decreases after the meter is inserted?
Current will be decreased because of the resistance of the ammeter added to the circuit's resistance. In other words total resistance increases.

You are just asking that let us assume you have connected 2 or 3 resistors in a circuit and the current flowing through the circuit and from all the resistors will be same but how?
If the resistors are connected in series, the total resistance will be the sum of the resistances of each resistor, and the current flow will be the same thru all of them. if the resistors are connected in parallel, then the current thru each resistor would depend on the resistance of that resistor, the total resistance would be the inverse of the sum of the inverses of the resistance of each resistor. Total current would depend on the voltage and the total resistance
What is the formula for total current in a series circuit?
Current = (Voltage across the circuit) divided by (Total resistance of the circuit). The current is the same at every point in the series circuit.
How do you connect a voltmeter in parallel circuit?
A voltmeter is used to measure potential difference across two points in an electrical circuit . The voltmeter is connected in parallel across the circuit element (resistance ) so that its inclusion in the circuit has negligible effect on total resistance and current flowing in yhe circuit A voltmeter has high resistance,if connected in series it will increase of circuit and reduce the current in the circuit
Do additional resistors affect current in a series circuit?
Yes, additional resistors affect current in a series circuit by increasing the total resistance, which decreases the total current.
What is a bleeder current?
The current left after the total load current is subtracted from the total current into the circuit. -From Principles of Electric Circuits by Floyd

As you don't specify how R1 & R2 are connected, it is impossible to give an answer to your question.
