1. An insulator is a material that: Slows electrical energy and allows thermal energy to pass Slows thermal and electrical energy from trensfering Transfers electrical energy and slows thermal energy Transfers thermal and electrical energy

## Step 1<br />An insulator is a material that does not allow the flow of electric current. This means it slows down the transfer of electrical energy. <br /><br />## Step 2<br />In terms of thermal energy, insulators also slow down the transfer of thermal energy. This is because they have a low thermal conductivity, which means they do not allow heat to pass through them easily.<br /><br />## Step 3<br />Therefore, the correct answer is "Slows thermal and electrical energy from transferring".
