6. Which of the following is a safety device.often represented by the symbol "F," used in electrical circuits to protect against excessive current? a) Capacitor b) Fuse C) Resistor d) Transformer Bos birak

## Step 1<br />The question is asking us to identify a safety device that is often represented by the symbol "F" in electrical circuits. This device is used to protect against excessive current.<br /><br />## Step 2<br />Let's examine each option:<br /><br />a) Capacitor: A capacitor is an electronic component that stores and releases electrical energy. It is not typically represented by the symbol "F" and is not primarily used to protect against excessive current.<br /><br />b) Fuse: A fuse is a safety device that is designed to protect electrical circuits from excessive current. When the current exceeds a certain threshold, the fuse will blow or melt, breaking the circuit and preventing potential damage.<br /><br />c) Resistor: A resistor is an electronic component that resists the flow of electrical current. It is not typically represented by the symbol "F" and is not primarily used to protect against excessive current.<br /><br />d) Transformer: A transformer is an electronic component that transfers electrical energy between two or more circuits. It is not typically represented by the symbol "F" and is not primarily used to protect against excessive current.<br /><br />## Step 3<br />Based on the above analysis, the correct answer is b) Fuse. A fuse is a safety device that is often represented by the symbol "F" and is used to protect against excessive current in electrical circuits.
