1. Resistance is equal to voltage divided by current.
Explanation: In an electric circuit, resistance is a measure of how much the flow of electric current is hindered by the material through which it passes. The resistance can be calculated by dividing the voltage (measured in volts) by the current (measured in amperes).

2. See Fig.1; compare circuit (a) with circuit (b); are they different?
Explanation: In order to compare circuit (a) with circuit (b), we need to refer to Figure 1. By looking at the diagram, we can visually analyze the two circuits and determine whether they are the same or different.

3. Circuit (a) includes a voltage source and two resistors.
Explanation: In circuit (a), there is a voltage source (which provides the electrical energy) and two resistors (which impede the flow of current). This information tells us what components are present in the circuit.

4. Any conductor offers resistance to the flow of current.
Explanation: A conductor is a material that allows the flow of electric current. However, even conductors offer some resistance (though it may be very low). Resistance is a natural property of materials, and it restricts the flow of current to some extent.

5. The elements in circuit (b) are connected in parallel.
Explanation: Parallel connection refers to a configuration in which the components or elements in a circuit are arranged so that the current can flow through multiple paths simultaneously. In circuit (b), the elements are connected in parallel, which means that the current can divide and flow through each element independently.

6. Draw a scheme of a series-parallel circuit.
Explanation: A series-parallel circuit is a combination of series and parallel connections. To draw a scheme of such a circuit, we need to arrange multiple components (resistors, voltage sources, etc.) in a way that some are connected in series (the current flows through them sequentially) and others are connected in parallel (the current divides among them). The specific configuration will depend on the given circuit setup.
