How the current and pressure coils of the wattmeer are connected in circuit to measure the power drawn by load?

The current coil is connected in series with the load. The voltage coil (the term, 'pressure coil' is rather archaic!) is connected in parallel with the load. The wattmeter's polarity markings must be taken into account, or the meter will read downscale (backwards).

What is used to measure the current in a circuit and how is it connected?
To measure the current in the circuit an ammeter is used and it is connected in series
A W pf capacitor is connected into a 240 V Hz circuit. what is the current flow in this circuit?
a 30 pf capacitor is connected into a 240v, 60 hz circuit. what is the current flow into the circuit
How can an ammeter be connected in a circuit and not effect the flow of current?
The ammeter does affect the flow of current in a circuit, however, the resistance of the ammeter is so small in comparison to the circuit that the effect is negligible. It is connected in series.
How to measure current?
Current in a circuit can be measured by using a device called ammeter that is always connected in series in the circuit in which current is to be measured.
A 9.0 volt battery is connected to a 4.0-ohm and 5.0-ohm resistor What is the current in the circuit?
If a 9.0 volt battery is connected to a 4.0-ohm and 5.0-ohm resistor connected in series, the current in the circuit is 1.0 amperes. If a 9.0 volt battery is connected to a 4.0-ohm and 5.0-ohm resistor connected in parallel, the current in the circuit is 0.5 amperes.
Is the amount of current that flows in the wire of electric circuit the same as the current that flows in the filament of the light connected in that circuit?
yes
How many amps in 11.000 volts?
The voltage tells you nothing about the current flow in amps, it's only the pressure sending current through a circuit. If a 11,000 volt supply is not connected to anything, the current is zero.
How is an ammeter connected in a circuit?
Series connect it within the line of the circuit for which you are interested in measuring the current flow.More detailSince we measure the flow of current IN the circuit, the ammeter must be connected in series with the part of the circuit for which you are interested in measuring the current flow.One of the ammeter's terminals must be connected to a point of the incoming current flow and its second terminal must be connected to the point of on-going current flow. To do this, cut the relevant circuit wire and connect one terminal of the ammeter to each end of the cut.
When wires are connected to the terminals of a battery. what causes electric current in the circuit?
The resistance of the load is what causes an electric current to flow in a circuit.
When the wires are connected to the terminals of the battery what causes electric current in a circuit?
The resistance of the load is what causes an electric current to flow in a circuit.
What happened when Volta connected the parts of his cells in circuit?
An electric current flowed around the circuit.
What happened when volta connected the parts of his cells in a circuit?
when he connected the parts he got an electric current.
