Can you pls answer activity 1
In the previous module, you have learned about current, resistance and resistivity, electromotive force, and the relationship of current and voltage using the Ohm's Law. It is emphasized that for ohmic materials, as the voltage increases, the amount of current also increases as resistance is held constant. The resistance of a conductor is dependent on the type of material, its cross-sectional area, and length. Likewise, resistance is also affected by 1 (This is a Government Property. Not for Sale.) temperature. In this module, you will apply the concepts of current, resistance, voltage, and the Ohm's Law to circuit. INTRODUCTION In your house, you illuminate your living room by turning on the switch. This is because you need to close the circuit for charges to move. Voltage provides the "push" for charges to move. Turning "on" an electric device means you close the circuit, while turning it "off breaks the circuit – making it open. АСTIVITY Activity 1: Objective: Directions: Basic Connection To identify the type of circuit connection. Observe the pictures. Complete the table by describing how the light bulbs are connected, and by translating the given circuit to its corresponding schematic diagram using circuit symbols.

From the result of the experiment, what can you infer about the total voltage as compared to the values of the individual voltage of the resistor? Write an expression that relates total voltage with the individual voltage across the resistor. 2. Compare the values of Ii and l2. What can you say about the value of the current for each resistor in the setup? 3. Calculate the ratio of the total voltage (Vuaa) and the equivalent resistance (Re) for each setup. How do the values of the ratio of Vstal and Reg compare with the I in each resistor? What can you infer from these values? (This is a Government Property. Not for Sale.)
