Forum: Comparison and Contrast
- A parallel or a series circuit?
Are these sentences true about a parallel or a series circuit? First, decide which is which and then write at least three sentences comparing and contrasting these types of circuit. Use appropriate comparison/contrast expressions and do not repeat the same expression twice. You can add any technical facts that you need.
1) The current of the circuit from the battery before reaching any component is the sum of all the current in the circuit after it passes through all the components.
2) The current of every component of the circuit is the same.
3) The voltage of the battery is the sum of all the voltage of the components in a circuit.
4) Comparatively more wire is needed to make the circuit.
5) Components are not functional if any of the components are damaged, because this disrupts the flow of current.

- A current or a voltage?
Are these sentences true about a current or a voltage? First, decide which is which and then write at least three sentences comparing and contrasting current and voltage. Use appropriate comparison/contrast expressions and do not repeat the same expression twice. You can add any technical facts that you need.
1) It is the potential difference in charge between two points in an electrical field.
2) It is the rate at which electric charge flows past a point in a circuit. In other words, it is the rate of flow of electric charge.
3) It is measured by an ammeter in amperes, aka amps.
4) It gets distributed over components connected in series.
5) It is the same across all components connected in parallel.

- An alternating current or a direct current?
Are these sentences true about an alternating current or a direct current? First, decide which is which and then write at least three sentences comparing and contrasting these two types of current. Use appropriate comparison/contrast expressions and do not repeat the same expression twice. You can add any technical facts that you need.
1) It is safe to transfer over longer distances.
2) It cannot travel very far.
3) Its frequency is zero.
4) Its frequency is 50Hz or 60Hz depending upon the country.
5) It reverses its direction while flowing in a circuit.
6) It is the current of magnitude varying with time.
7) Electrons move steadily in one direction or 'forward'.
8) It is obtained from a generator.

- An electric field or a magnetic field?
Are these sentences true about an electric field or a magnetic field? First, decide which is which and then write at least three sentences comparing and contrasting these two types of field. Use appropriate comparison/contrast expressions and do not repeat the same expression twice. You can add any technical facts that you need.
1) It is created around a moving electric charge and magnets.
2) Its units are Newton per coulomb, or volts per metre.
3) Its units are Gauss or Tesla.
4) Its movement in the electromagnetic field is perpendicular to the electric field.
5) It generates reactive power.
6) It is created either by monopoles or dipoles.
7) It absorbs reactive power.
8) It is created by dipoles only.
